onsemi Surface Mount Positive Voltage Regulator 1.6-5.5V Input, 90µA Quiescent Current 8-Pin NCV8177AMTW110TCG-A642

onsemi NCV8177AMTW110TCG-A642 is a high-performance surface mount positive voltage regulator series designed for efficient power management with an operating input voltage range from 1.6 V to 5.5 V. This device features a typical low quiescent current of 90µA, making it ideal for battery-powered applications including Li-ion batteries and post-regulation scenarios. Its very low dropout voltage of 200 mV at 0.5 A load (for the 1.8 V version) ensures minimal power loss and maximizes battery life.

The NCV8177 series provides design flexibility with several fixed output voltage options and a stable performance aided by an internal soft-start mechanism that limits in-rush current. This protects both the device and the surrounding circuitry from damage. With a high output voltage accuracy of ±0.8% at room temperature, this voltage regulator ensures precise voltage regulation critical in sensitive electronic instrumentation.

Thermal shutdown and current limit protections further enhance device reliability by preventing overheating and excessive current flow. The compact 8-pin surface mount package, measuring 2.1 mm by 2.1 mm with a height of 750 µm, saves valuable PCB space and reduces system costs. Operating at a maximum temperature of 125°C and approved under the automotive standard AEC-Q100, it is suitable for rugged automotive applications as well as general industrial and consumer electronics.

This voltage regulator excels in noise-sensitive circuits such as lighting systems, instrument equipment, cameras, camcorders, and various sensor devices, providing high 75 dB PSRR at 1 kHz to suppress power supply noise effectively. Its stability with small 1 µF ceramic capacitors further enhances its integration into compact electronic designs.
